Research Project: Application of Lidar Technology for Measurement of Emission and Dispersion from Agricultural Systems Project Number: 3625-11610-001-12
Project Type: General Cooperative Agreement

Start Date: Sep 23, 2010
End Date: Jul 31, 2015

Objective:
1. Apply lidar technology to the development of remote sensing methods for measuring particulate emission and dispersion from agricultural systems. 2. Develop dual lidar systems to improve the measurement of emissions and their dispersion from individual sources and whole facilities or management operations. 3. Apply lidar to the measurement of water vapor and other gases from agricultural systems.

Approach:
To address this problem we propose to follow these steps in developing this remote sensing approach for particulate emissions from animal production facilities: 1) produce qualitative 2-D images of plume emission and dispersion from a CAFO. 2) quantify statistical or turbulent properties of the flow field of a CAFO. 3) establish a protocol for a remote sensing approach to measure particulates at a CAFO. 4) conduct multiple 24-hour campaigns to capture all diurnal stability cases. 5) convert 2-D qualitative information to quantitative data using results from the Electrical Low Pressure Impactor (ELPI) to define size fractionation of the particulates. 6) using the size fractionation results from 5 compute flux estimates at the whole facility scale and compare with available published data; 7) using the first 6 steps, apply the remote sensing approach to cropping surfaces to compare tillage and harvest practices, i.e., particulate flux emissions at the field scale.
